8 Claims. (Cl. 30-30) My invention relates to improvements in haircutting and trimming devices.

The cutting and trimming of air as usually practised entails the use ofa pair of scissors and a comb, the scissors being actuated by one handwhile the comb is manipulated by the other hand of the operator.

it will be clear that if a. person endeavours to cut or trim his ownhair it is with great difiiculty the act is accomplished and usuallywith indifierent results.

To overcome the difiiculties encountered I have contrived to associate acomb with a safety razor blade in such a manner that a person may cut ortrim his own hair.

The arrangement of comb and razor blade is such that not only may hairbe cut or trimmed but a graduated or shingle effect may be obtained.

Hair when properly cut should increase progressively in length from theneck and temples to the top of the head and an object of my invention isto be able to adjust the comb relatively to the razor blade so that mydevice wiil be adapted to meet all conditions encountered when cuttingor trimming hair.

Another object is to prevent the razor blade edges coming in contactwith the scalp, even when a close out is desired.

Another object is to assemble the comb relatively to the razor blade sothat the device may be taken apart quickly and in a simple manner topermit stropping of the razor blade, if desired, or replacing it by anew one, and also make the combs available for cleaning.

Another object is to arrange the parts so that they are open toinspection at all times.

My device is such that it may be used not only by individuals but may beused with advantage in beauty parlours and in barber shops.

So that the nature of my invention will be clearly understood I haveillustrated an embodiment of the same and described it in detail in thefollowing specification in which:

Like characters of reference refer to like'parts in the several figures.

Referring to the drawings, 1 represents part of the holder of myimproved hair cutter and trimmer formed at one end with a hand grip orshank 2, the other end 3, being flattened. The back or lower face of thefiattened end 3, is convex in cross section as shown at 4, while theupper face 5, is a flat or plane surface provided centrally with 'alongitudinally extending rib 6. Arranged in alignment with this rib butspaced therefrom is a small rib or projection '7 having undercut ends 8and 9.

At the junction of the hand grip 2, and the fiat end 3, an ellipticalring 10, is slidably mounted and this ring is provided with a set screw11 adapted to secure the ring in locked position as will be describedhereafter.

A razor blade 12, of the safety type is mounted on the plane face 5, ofthe end 3, of the holder and the front portion of the blade is slid backto frictionally engage the undercut portion 9 of the projecting rib '7,and the central rib 6, extends through the usual elongated aperture inthe razor blade. In this position the razor blade lies flat on the upperplane face 5, of the flat end 3, of the holder.

A razor blade clamping plate 13 is formed at one end with a slot 14adapted to be slid along the projection 7, and the rear end 15, of theslot engages the undercut end 8, of the projection 7. The lower or innerface of the plate 13 is provided with an elongated recess 16 whichengages the rib 6, on the end 3, of the holder.

The other end of the clamping plate 13, is provided with a short centralnb 17, flanked by two ribs 18, from the latter of which extends twolateral hook projections 19, which are adapted to engage one end of theslidable elliptical locking ring 10.

The upper face 20, of the clamping plate 13, is convex in cross sectionand engages the under concave face 21, of the cover plate 22, which isformed at its front end with a depending elliptical ring 23, adapted tofit over the end of the flat portion 3, of the holder and its icoactingclamping plate 13.

The end of the cover plate 22, remote from the ring 23, is formed with apair of longitudinally extending fingers 24, terminating in downwardolfset ends 25, the fingers 24, being adapted to lit in the groovesformed between the ribs 17, and 18, while the offset ends 25, overhangthe edge of the clamping plate 13.

In this position the cover plate 22, the clamping plate 13, and the end3, of the holder are held in assembled position by sliding theelliptical ring 10, into position over the fingers 24, and ribs 17 and18, whereupon the ring 10 is secured by the set screw 11.

The longitudinal edges 26, of the cover plate 22, project over the sidesof the clamping plate 13, and below the lower face thereof and engagethe edges of the razor blade 12, to deflect or bend the edges of theblade down- 3 wardly (see Fig. 14) and so place the cutting edges of therazor blade at the correct angle and in position to contact the hairbeing cut.

It will be seen that the holder, razor blade, clamping plate and coverplate are held firmly in place by thetwo rings 23 and and lateraldisplacement of any of these members cannot take place. Mounted on thecover plate 22, are two spacing blocks 27, having their upper and lowerfaces formed concave as shown at 28, and 29, the lower face snuglyfitting and straddling the cover plate 22. The lateral faces 39, of eachspacing block 27', slope outwardly and downwardly and are formed with adownwardly extending recess or channel 31.

The spacing blocks 27 are located in spaced relation adjacent theopposite ends of the cover plate 22.

Straddling the upper face of each spacing block is a strip of metal orother suitable material 32, which is shaped to snugly fit the upperconcave face 28, of the spacing block and a bolt 33, passes through thecover plate 22, the spacing block 27 and the strip 32, to firmly holdthem in position as an assembled unit. The ends 34- of the strip 32, areoliset downwardly forming arms spaced from, but in parallelism with thelateral faces 30, of the spacing blocks and the strip is fitted at eachside with an adjusting screw 35, which is journalled in the strip buthas its depending threaded shank 36, located in the recess or channel31. The threaded shank 36, makes threaded engagement with the eyelet 37which is formed with a radial pin 38, designed to be secured to theupper portion of the comb 39.

As each end of the comb is supported in this manner, the combs may bemoved downwardly parallel with the ends 34 of the strip 32 or the combsmay be tilted endwise. The teeth 49, of the comb normally extendslightly below the cutting edge of the razor blade 12, and both screws35, may be rotated to project the comb into the desired position inwhich the teeth 40, will project below the cutting edge of the razorblade and so position the razor blade at the proper distance from thepoints of the comb teeth to permit the hair being cut to the desiredlength. In some cases it may be desirable or even necessary to adjustthe comb by tilting it longitudinally so that one end of the combprojects farther below the razor blade than the other end and this isdone by adjusting one screw to obtain the desired positioning of thecomb. The device being double sided it may be manipulated with easebyeither the right or left hand of the operator. When the device is in usethe combs 39, are adjusted and the operator holds the device in hisright or left hand depending on which side of the head the hair is beingcut or trimmed. The operator now proceeds to move the device upwardsfrom the neck thus giving this upward motion to the comb 39 whichpreceding the cutting edge of the razor blade 12 lifts or tilts the hairupwards against the natural lie of the hair, so that the hair comes incontact with the cutting edge of the razor blade and a clean cutting ortrimming of the hair results.

As the operator proceeds with the cutting operation further up the headthe combs 39 may be adjusted in the manner previously described so thatthe length of the hair will progressively increase towards the top ofthe head. The operator may give the device an upward curving motion andso obtain the graduation of hair cut desired.

If a very close hair cut is desired it is only necessary to adjust thecombs 39 upwardly relatively to the razor blade 12 to obtain therequired position of blade and comb.

It is believed that the construction and advantages of the structureshown may be apparent from the foregoing paragraphs taken in conjunctionwith the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it isunderstood that minor changes in the construction, combination andarrangement of cooperating parts may be resorted to within the scope ofwhat is claimed without departing from the spirit of the invention.
